Trump anticipates 'unfair' CNBC debate

Hours ahead of CNBC's Republican presidential debate on Wednesday, Trump anticipated the event would be "unfair" toward him for unspecified reasons.

On Twitter, Trump told his more than 4.5 million followers that he expected the deck to be stacked against him.

"After a great evening and packed auditorium in Iowa, I am now in Colorado looking forward to what I am sure will be a very unfair debate!" Trump wrote.

"CNBC continues to report fictious [sic] poll numbers," he said in a second tweet. "Number one, based on every statistic, is Trump (by a wide margin). They just can't say it!"

Since announcing his campaign for president in June, Trump has led the GOP field in nearly all national and early primary state-level polls. But some recent polls show he lost his front-runner status to retired neurosurgeon Ben Carson, who like Trump, has never held public office.
